Do you have an air bag light flashing? Does the horn still work? If the answers are yes and no, you have a bad clockspring. Does the speedo work correctly? The cruise control is controlled by a speed sensor in the top of the differential, so it's possible that you've got a loose wire somewhere preventing it from working. If it's an aftermarket system then you'll need to crawl under the van and solder all the connections where there are butt connectors. This is a common mistake made by dealerships that install the aftermarket systems to please their customers. Water gets into the connectors and corrodes the wires and connector resulting in loss of contact.

When my crusie went out in my 1992 E150 it turned out to be the buttons in the steering wheel had worn out. To replace you disconnect the battery and let it sit for a while to de-energize the air bag. I let mine sit overnight. Remove the air bag and the buttons are right below. Prior to remaoval, there is a diagnostic procedure to figure out whether the buttons are bad. You can find it in the factory manual. In order to run through the procedure you have to disconnect a harness thats below the master cylinder and jump pins in the connector checking for continuity and/or voltage between various pins. I broke the plastic connector lock on mine, now the connector is held together with a plastic quick tie.

everything is workin fine and its a factory cruise control the wire on the diff is that aftermarket only? As for the buttons being bad did your still light up when they were bad mine still light up at night
thanx

Check the brake position switch. If the contacts are stuck closed it will keep the system from working. There is also a normally closed brake pressure switch on the front of your master cylinder that is supposed to open and deactivate the system under heavy braking if the brake position sensor fails.

Most of the time a cruise control stops working because the buttons wear out. The more often you use your cruise control, the more likely the buttons willl be shot. There is a 10 step procedure you run through, we got up to 9 or 10 before we caught the failure.

One other thing to check is where the cruise cable attaches with the throttle cable on top of the engine. The connector on mine broke so I latched it down with a quick-tie rather than replace the whole cable. That was 30,000 miles ago.

Here is the diagosis procedure as promised.

A1 VISUAL CHECK

Perform visual check.
GO to «A2».

A2 SETUP

Disconnect harness connector from the servo assembly.

Use Rotunda Digital Volt Ohmmeter 014-00407, or equivalent, to make the specified measurements at the harness connector.
GO to «A3».

To tell you the truth i havent got into it yet i have 2 kids under the age of 3 time is limited but the cruise is on my list im heading up to the fall carlisle show and would love to have it working by then thanks for showing interest.
